Abstract: A remote control system for controlling electrical apparatus in customer premises (5 of Figure 1) comprises a home control interface (15) for connection by way of network termination equipment (12), e.g. a telephone socket, to a communications line (4) to a telephone exchange (3 of Figure 1) . The home control interface (15) is responsive to signals received from a hom e control platform (8 of Figure 1) connected to the telephone network to contr ol electrical apparatus by way of module interfaces (16). The home control interface is arranged on demand to transmit signals to the communications li ne (4) indicative of the current status of each piece of electrical apparatus connected to the system. The consumer may use a telephone (14) to pre-record  a definition of the electrical apparatus attached to each connection on the module interface (16) which, when remote control requests are forwarded to t he home control platform (8 of Figure 1) are used to define the respective swit ch and to announce its status to the caller. The home control platform (8 of Figure 1) has capability of storing substantial quantities of data defining changes required in switching at different times.

Title: System for transmitting data from inside a tire to a remote receiver
Inventor: WILSON PAUL B
IPC: G08C17/00
Filed: 1998-12-18
Granted: 2009-02-24
Abstract: A method for monitoring various engineering conditions of a pneumatic tire such as temperature, pressure, tire rotation and other operating conditions of the tire. A tire tag is mounted on the interior of the tire within the pressurizable cavity and contains the stored data and sensors for detecting certain conditions within the cavity. A separate transponding device is mounted on the tire rim. The tire tag contains a battery, an antenna and stored data pertaining to the tire. The transponding device uses electronic circuitry which collects data from the tire tag. The tire tag is actuated by transmitted radio frequency waves from the transponding device, which data is retransmitted by the transponding device to the remote location by an antenna which extends from the transponding device through the rim to a location externally of the tire.

Filed: 1997-06-17
Granted: 2003-03-11
Abstract: Disclosed is an absorbent article, such as a sanitary napkin, incontinent device, or the like. The absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent article further comprises a pair of longitudinally extending cuffs disposed on the body surface of the topsheet on each side of a longitudinal centerline of the absorbent article. The cuffs comprise an elastic member and a resilient member and are joined to at least one of the topsheet and the backsheet in a longitudinally elastically elongated state. The elastic member preferably comprises first and second regions which are visibly distinct from each other.  The first region comprises at least two substantially planar portions and the second comprises a plurality of raised, rib-like elements. In a particularly preferred embodiment of the present invention, at least one of the substantially planar portions of the first region of the bands of web material extends in a substantially longitudinal direction and at least one other of the substantially planar portions of the first region of the elastic member is oriented at an angle with respect to the longitudinal direction. The resilient member is soft yet sufficiently resilient to resist the compressive forces applied to the cuffs by normal wearer movement. The resilient member is positioned sufficiently close to the body surface of the topsheet to also provide resistance to bending that may also be caused by normal bodily movements.

Granted: 2011-02-08
Abstract: The cloning of the Mlo gene of Barley, mlo mutants, and homologues from other species including rice and Arabidopsis thaliana enables manipulation of pathogen defence responses in plants. Nucleic acid and polypeptides are used in the production of transgenic plants in which the pathogen defence response is modulated, particularly stimulated.  Various approaches enable diagnostic determination of the presence of susceptibility or resistance alleles in plants. Compounds able to modulate a defence response by interaction with Mlo or mlo protein are identifiable using assays involving the protein or fragments thereof.

Granted: 2001-12-04
Abstract: A control device for controlling the running behavior of a four wheeled vehicle has a mathematical tire model of each wheel defining a relationship between longitudinal and lateral forces vs. slip ratio, synthesizes the mathematical tire model at zero slip and a control input from an outside running behavior controller such as a spin controller or a driftout controller to generate nominal values of longitudinal force, lateral force and yaw moment of the vehicle body, and controls the slip ratio of the wheels through cyclic adjustment so as to approach the differences between the nominal values and the actual values in the longitudinal force, lateral force and yaw moment of the vehicle body to the corresponding differences of those parameters due to differentiation thereof by the slip ratio based upon the mathematical tire model.

Title: Dimpled circular saw blade
Inventor: PHILLIPS GREGORY A
IPC: B23D61/12
Filed: 1997-09-08
Granted: 2003-09-16
Abstract: An improved circular saw blade having first and second planar surfaces is provided which has a plurality of dimples which formed one or both of such surfaces o f the blade. The dimples each have a perimeter and include a circumferential ridge which extends above the surfaces of the body of the blade. When a side load is applied to the wo rk piece, the ridges contact one of the walls defining the kerf being cut that is forced b y the load against the blade, so that the surface of the body of the blade is spaced from the wall. The dimples are preferably formed by cold working the blade, which stiffens the blade, a nd reducing the vibration of the blade during the cutting procedure. The dimples and their ridges also provide greater heat dissipation, and tend to provide a laminar flow of air over the surface of the blade, acting much as the dimples of a golf ball.

Filed: 1999-06-03
Granted: 2009-01-13
Abstract: The present invention is a device and a method for boring a perfusion channel from a coronary artery into a cardiac muscle of a patient. Structurally, the present invention includes a positioning catheter, anchor means and a cutting catheter. The cutting catheter includes a plurality of blades and is advanceable through a deployment lumen of the positioning catheter. Advancement of the cutting catheter through the deployment lumen causes a distal end of the cutting catheter to project laterally from the positioning catheter. In use, the positioning catheter is positioned within the coronary artery. The anchor means is then expanded to anchor the positioning catheter within the artery. The cutting catheter is then advanced through the deployment lumen to bore one or more perfusion channels in the myocardial tissue.

Title: A universal implant blank for modifying corneal curvature and methods of modifying corneal curvature therewith
Inventor: PEYMAN GHOLAM A
IPC: A61F2/14
Filed: 1998-03-11
Granted: 2008-11-18
Abstract: This invention is a universally sized blank (18) made of organic or synthetic material that can be placed on an exposed inner surface of a live cornea and ablated with a laser beam (27) to be altered to a particular shape. A flap-like portion of the live cornea is removed to expose an inner surface of the cornea, and the blank (18) is positioned on the exposed inner surface of the eye. A laser beam (27) is directed onto certain portions of the blank (18) that are selected based on the type of ametropic condition (i.e., myopia, hyperopia or astigmatism) of the eye needing correction, so that the laser beam (27) ablates those portions, and thus reshapes the blank. The laser beam (27) can also be directed onto certain portions of the laser surface of the cornea to ablate those surfaces of the cornea. The flap-like portion of the cornea is repositioned over the remaining portion of the blank (18), so that the remaining portion of the blank (18) influences the shape of the reattached flap-like portion of the cornea and thus modifies the curvature of the cornea.
